Warning! S23ultra users - the last September security update messed up the LTE modem
Long story short, after the September security update, my phone started to drain overnight 8x faster than before...I was losing 2-3% overnight, now it went to 20%. I wiped cache partition, went to great lengths factory resetting the phone, put it in safe mode to rule out a rogue app...NOTHING. In a moment of desperation, I set the bands to WCDMA/GSM only and the drain is gone!! Note that I have 5 LTE bars at home (band 12, RSSI > -95dBm) so signal strength has NEVER been a problem in the 5 years since I joined Videotron. I'm not on a Partner network at home. The only rational conclusions that either Videotron made changes to the modem code, or Samsung did and it affected Videotron bands. Either way, no one tested this seriously before blasting it to unsuspecting customers. Kira can we please ensure that next time around, this issue gets addressed and tested? I spent a ton of time troubleshooting, so I'd rather not do it again. It would be a lot easier to just change carriers. I'm available with a ton of notes and information if someone technical wants to get in details. BTW, I work for a telecom equipment manufacturer.Solved3.8KViews0likes7Comments
